Oth diab with prolif diab rtnop without macular edema, l eye

This code signifies a form of diabetes mellitus, not type 1 or type 2, that is complicated by the presence of proliferative diabetic retinopathy in the left eye. Proliferative diabetic retinopathy is an advanced stage of diabetic eye disease characterized by the growth of new, abnormal blood vessels on the retina. Importantly, there is no associated macular edema in this specific diagnosis.

Use this code when a patient has a documented diagnosis of "other specified diabetes mellitus" and an ophthalmological examination confirms proliferative diabetic retinopathy affecting only the left eye, with no evidence of macular edema. Documentation should clearly distinguish the type of diabetes and specify the laterality and absence of macular edema.

• Always ensure the documentation specifies "other specified diabetes mellitus" and not type 1 or type 2.
• Verify laterality; this code is specific to the left eye. Use the appropriate code for the right eye or bilateral involvement.
• Confirm the absence of macular edema; if present, a different code reflecting macular edema would be required.
